Why the Duisburg convoy escort could not recover

The loss of all seven merchant ships was difficult for the Axis to replace because it lacked a comparable mass-production programme to the American Liberty ships. Force K began withdrawing after completing its search, although the covering force claimed to have driven it away. HMS Upholder then struck Libeccio, which had taken survivors aboard; Euro took the damaged ship in tow before it sank. Italian criticism focused on escort coordination, while the interpretation offered here also faults the assumptions underlying the plan. The aftermath compounded the lost cargo with further losses among the escorts and rescue effort.
